Overview
The document provides technical specifications and features of NEU rotary airlocks, which are designed to ensure continuous discharge of dust and chips from hoppers. These airlocks are particularly effective when integrated with pneumatic conveying systems.

Specifications
The rotary airlocks come in three sizes: 300x300, 300x400, and 500x500. They maintain an airtight seal, crucial for system efficiency, and are ATEX certified (FTZU 07 ATEX 0070X) according to NF EN 15089 standards. They are classified as 'flame break' and explosion pressure shock resistant for internal zone 20 and external zones as per plant requirements.

Efficiency
The airlocks feature an 8-blade rotor and operate at a high rotation speed of 21 rpm, making them highly airtight and capable of handling large material volumes.

Simplicity
The design emphasizes robust construction, ease of use, and reduced maintenance needs.

Dimensions
The document provides detailed dimensions for each model, including weight and specific measurements for installation.

Range and Performance
The airlocks are equipped with a moto-reducer and have varying dust exhaust capacities depending on the model. The output torque is 505 Nm for the 300x300 and 300x400 models, and 684 Nm for the 500x500 model, all operating at an output speed of 21 rpm. Motor power is 1.1 kW for the smaller models and 1.5 kW for the largest, with a motor speed of 1500 rpm. Dust exhaust capacities are provided for 100%, 75%, and 50% operational levels.
